"Giancarlo is an incredibly sweet, generous actor and incredibly gifted, amazing actor, so it's wonderful to have him around," Odenkirk said. "And it's wonderful to get the story closer to the world of Breaking Bad, and it's not just Giancarlo.

"There are other characters from that show that are starting to appear, so that is super-exciting, and it raises our stakes, and it raises our game at Saul.
